Many places in Ningxia issued orange warnings for sandstorms. Why did sandstorms appear in multiple cities at the same time?

Following the severe sandstorm in Beijing, several cities in the north issued sandstorm warnings. Data from the Ningxia Meteorological Observatory on March 15th showed that sandstorms began to occur in Yinchuan, Shizuishan and other places starting from midnight on the 14th, with visibility at 100 meters. Between 500 meters and 500 meters, many netizens even said that they were woken up by choking in the middle of the night. Some netizens joked that girls don’t need to apply powder when they go out today. It’s still natural to put makeup on after exposing your face to the air for ten seconds. It's wheat color. The Ningxia Meteorological Observatory issued 14 orange sandstorm warnings in succession at 4 a.m. on the 15th, and requested all relevant departments to pay attention to the impact of strong winds and dust and reduced visibility. Sandstorms may continue and you need to take precautions when going out. Work. Sandstorms occurred in 12 northern provinces

The Central Meteorological Service upgraded the yellow sandstorm warning in the early morning of March 15. It also reported that 12 provinces in northern my country will be affected by sandstorms, including Beijing, Tianjin, Hebei, and Xinjiang. , Inner Mongolia, Heilongjiang, etc. will all experience obvious sand and dust weather. This is the first large-scale sand and dust storm that has occurred in my country in the past ten years. The air index in North China and Northwest China has been explosive for 15 consecutive days. The source of the sandstorm

According to information from the Satellite Imagery and Ground Monitoring Information Comprehensive Assessment Division of the Desertification Detection Center of the Forestry and Grassland Administration of my country, the source of this sandstorm came from Mongolia. On the morning of the 14th, a sandstorm occurred in southwestern Mongolia. Sandstorms gradually move southward with the airflow and invade cities in northern my country. According to the news released on the website of the General Administration of Economic Situation of Mongolia, the sandstorm has caused 9 deaths and 586 people missing. The sandstorm occurred in Mongolia and the temperature rose at the beginning of the year, but there was no rainfall, causing the ground to be dry, but the vegetation has not yet grown. The surface is exposed, and the spring monsoon is coming. The sand on the ground rises to form a sandstorm. The reason for the simultaneous occurrence of sandstorms in the north

The occurrence of this sandstorm is very coincidental and has the characteristics of wide range and high intensity. It also invaded twelve provinces in northern my country at the same time. This has puzzled many people. If sandstorms from Mongolia mostly hit North China, why are the northwest regions also affected? In fact, sandstorms also occur in northwest my country every spring, but they are not as strong as this one. The occurrence of sandstorms in many places at the same time is closely related to the monsoon climate and temperature. The northern part of my country has a temperate continental climate. Westerly winds prevail in March and April every year. In addition, with the arrival of spring, the temperature in northern my country and Mongolia rises and the precipitation is low. There is too much exposed sand on the surface. Under such conditions, strong winds roll up the exposed ground. Dust forms sandstorms. Therefore, driven by the monsoon, 12 provinces in the entire northern region of my country will encounter sandstorms at the same time.
